Recycled Cardboard Cooler Boxes

These Recycled Cardboard Cooler Boxes($15) made from 70% recycled cardboard and the inside and outside of the box are covered with a ‘NorSheild’ waterproof coating that makes it weatherproof and reusable. With just two bags of ice they’ll keep food and beverages cold at around 41°F degrees for 36 hours when ambient temperatures are around 77°F outside. (That 36 hours obviously gets a lot shorter when the thermometer rises.)
